Judaism has nothing to do with race-there are Jews of every race-but it does have to do with family. Jews are members of Abraham's family. Not only tradition, but a great deal of DNA evidence support this claim. To insist that Jews adopt the criterion of "belief" for membership is to rule that God must act in accordance with a human court's notion of the permissible range of God's behavior. No wonder the Reform Jews and the British Humanist Association support this.

3) And, it seems more likely that that admixture arrived via maternal lineages, that is, gentile female ancestors (the mtDNA results are somewhat confused, but the Y lineages seem to be relatively strongly Middle Eastern in provenance in comparison to total genome content).

In light of the fact that the debate is over the validity of the criterion of maternal descent as to "Who is a Jew," it seems deceptive to appeal to genetics when that field opens up more questions in regards to Jewish tradition than it closes. Of course, this sort of shell-game is normal behavior for Spengler. Someone should really put a "For Entertainment Purposes Only" sticker on his blog.
